  • Patent number: 8932280
    Abstract: Systems, methods, and instruments associated with controlling the operating modes of an electrosurgical instrument using control signals delivered in a wireless manner from the electrosurgical instrument to an electrosurgical generator. The electrosurgical instrument transmits wireless control signals to the electrosurgical generator to initiate delivery of electrosurgical energy. The control signals are delivered to the electrosurgical generator without the need for a conductive cord extending between the electrosurgical generator and the electrosurgical instrument. The energy is delivered to the electrosurgical instrument, in response to the wireless control signals, along a path through an electrode and the physician utilizing the electrosurgical instrument and/or a conductive path external to the physician. The electrode upon which the physician rests provides a path for the electrosurgical energy and optionally prevents burning of the physician during an electrosurgical procedure.

  • Patent number: 7837680
    Abstract: An electrosurgical return electrode for use in electrosurgery. The return electrode is self-limiting and self-regulating as to current temperature and temperature rise so as to prevent patient trauma. According to one aspect of the invention, an inductor is coupled in series with the electrosurgical return electrode. The inductor is configured to optimize the flow of the electrosurgical current by minimizing the effective bulk impedance of the electrosurgical return electrode when the amount of contact area between the patient and the electrosurgical return electrode is sufficient to conduct electrosurgery. According to another aspect of the present invention, a conductor member is adapted for use with circuitry that indicates to a user when the contact area between the patient and the self-limiting member and/or return electrode is below a given threshold.

  • Publication number: 20100258565
    Abstract: The present invention provides a safe means for disposing of many kinds of medications and other substances so as to mitigate the many hazards associated with flushing them down the toilet, pouring them down the sink or placing them in the trash. For example, the inventive device comprises a closeable container into which pills, capsules or liquids may be placed. Once filled or as otherwise desired, this container may be reliably sealed prior to transporting it to a reclamation place suitable for processing and/or neutralizing the chemicals, or prior to placing the entire container in the trash. A reliably sealed container in the landfill would inhibit drugs from contaminating the water supply.

  • Patent number: 7367971
    Abstract: A removable semi-insulating sheet for use in self-limiting electrosurgical return semi-insulating sheet for use with electrosurgery. Through the selection of impedance characteristics for the electrode materials of the principal body of the semi-insulating sheet, and through tailoring of semi-insulating sheet geometries, the return electrode of the present invention is self-regulating and self-limiting as to current density and temperature rise so as to prevent patient trauma. The semi-insulating sheet has an effective bulk impedance equal to or greater than about 4,000 ?·cm. The effective bulk impedance of the sheet may arise from resistive components, capacitive components, inductive components, or combinations thereof. The configuration of the presently described return electrode allows the electrode to self-limit the electrode's current densities, thereby preventing burning of a patient during surgery.

  • Patent number: 7255263
    Abstract: An electrosurgical apparatus having a counter/lockout mechanism that monitors the number of sterilization/use cycles the electrosurgical apparatus undergoes and indicates the number of sterilization/use cycles that have actually been performed. The counter/lockout mechanism includes a temperature actuated element actuated in response to each sterilization cycle and a mechanically actuated element in response to a use cycle to effectuate a change of one or a plurality of indicia. The counter/lockout mechanism causes a single increment or decrement for each sterilization/use cycle that has been completed while also impeding use of the electrosurgical apparatus when the electrosurgical apparatus has undergone a predetermined number of sterilization/use cycles. In one embodiment, the distance of movement of the mechanically actuated element when fully actuated is greater than the distance the indicator moves when illustrating a change in the number of remaining uses.

  • Patent number: 7169145
    Abstract: An electrosurgical return electrode for use in electrosurgery. The return electrode is self-limiting and self-regulating as to maximum current and temperature rise to prevent patient trauma. An inductor is coupled in series with the return electrode. The inductor counteracts at least a portion of the impedance of the return electrode and the patient to optimize the flow of the current when the amount of contact area between the patient and the return electrode is sufficient to perform electrosurgery. The inductor may also be variable to allow the overall impedance of the electrosurgical circuit to be adjusted and tuned to work properly and safely with a particular patient and the other equipment used to perform electrosurgery. A conductor member operates with circuitry that indicates to a user when the contact area between the patient and the self-limiting member and/or return electrode is below a given threshold.
